Some recent re-examinations of this fern in connection with 

 r. Pringle's 827 from Mexico have led me to remove it alto- 

 gether from C. lajitigznosay under which species it was first pub- 

 lished as a variety, for the purpose of calling the attention of 



California botanists to its existence, and to restore it to specific 

 rank. 



Its history and description having already been fully pub- 

 h"shed (/. c), it seems unnecessary to more than briefly recall 

 attention to its essential specific characters here. These are, 

 primarily, in its creeping root-stocks, and secondarily, in the 

 scale-Iike fibres mixed with its tomentum, as against the tufted 

 root-stocks, and freedom from scale-like fibres in the tomentum 

 of C lamtginosa. 



There still remains a reasonable probability that it may ulti- 

 mately prove to be a form of (7. Parishii, with the scales of the 

 rachis reduced to mere fibres. But this is a point of which 

 the satisfactory determination requires more specimens of the lat- 

 ter species than are now in existence, and until a re-discovery oi 

 that now rare fern supplies such material, it will be as well to 

 consider the present one as a fairly good species.
